Frequently Asked Questions
SKU: VW Upgrade Kit
Upgrades your existing BMS Stage1 to an EA888 JB4 system. The JB4 features CANbus connectivity for more advanced tuning, direct AFR control, advanced safety systems for boost, air/fuel ratio, fuel trims, engine knock, boost mapping by gear for improved traction, integrated water/meth control, and much more.
The upgrade kit cost is $175 outright. There is no longer a core exchange program available. After the upgrade, you can keep your old Stage1 board as a spare/backup. This JB4 requires exclusive OBDII/CANbus access while tuning is enabled and is not compatible with various CANbus-enabled boost gauges or 3rd party devices that also require OBDII/CANbus.
When ordering, use the drop-down menu to specify left or right drive hand and your Stage1 hardware version. Vehicles in the USA and most other countries are left-hand drive (LHD), while the UK, AU, SA, and a few others are right-hand drive (RHD). For the Stage1 hardware version, systems purchased after approx 11/1/16 are REV2 and can be identified by an unused black Molex/2 position connector already incorporated into the harness. Check the installation guide below for additional information on identifying your existing hardware.
